I have AT&T 4G HSPA+ service in a small town and noticed they are currently working on a tower about a mile away. While it's not currently affecting my signal, service, or data speeds, I wonder what kind of upgrade they are doing to it. I know they are rolling out LTE and wonder if that is what they are doing or if they could possibly be just upgrading it to HSPA+. I receive a signal from different towers than that one, but I can only think that if they are going to update a tower, especially with hardware, that they would only be converting it to LTE now.

For the past few days they have had 2 cables running from the top of the tower's antennas down to a trailer. Also, I noticed multiple cardboard boxes and also new antennas laying on the ground that have yet to be put up. Could they possibly just be adding extra capacity for the area?

Just wondering if anyone has any insight as to what their current strategy is, if they are updating towers to only LTE or if they are continuing to add HSPA+ towers to areas that currently already receive more than enough "4G" coverage. I think it would be weird that they would be adding it right outside a major city vs updating a tower within the city that currently does not receive AT&T LTE coverage.

I believe this specific tower is owned by "New Cingular" as it is listed on the atttowers.com website. The other towers I access (most being "4G") are outsourced to 'FiberTower' and 'Metropolitan Area Networks'.
